A waste corn cob core-derived SiO2 @ graphene-like carbon nanocomposite and its application in lithium-ion battery

A waste corn cob core-derived SiO 2 @ graphene-like carbon nanocomposite (CCC) has been synthesized by a hydro-thermal and high-temperature carbonization process. The CCC material is carbonized at 900 °C (CCC-900). The SiO 2 nanoparticle with a granule size of 100–200 nm could be grown on the graphe...

Description
Summary:A waste corn cob core-derived SiO 2 @ graphene-like carbon nanocomposite (CCC) has been synthesized by a hydro-thermal and high-temperature carbonization process. The CCC material is carbonized at 900 °C (CCC-900). The SiO 2 nanoparticle with a granule size of 100–200 nm could be grown on the graphene-like carbon nanosheets. The BET-specific surface area can be calculated to be 481.81 m 2  g −1 . When it is used as an anode material for lithium-ion battery, the CCC composite can display the foremost discharge capacity of 2051.5 mAh g −1 at 200 mA g −1 and the maintain capacity of 125 mAh g −1 after 200 cycles. The high foremost discharge capacity could be attributed to the synergistic effect of SiO 2 nanoparticles and graphene-like sheets.
